Prevent Accidents and Emergencies

Correct answer: A. Saving work regularly

A sudden power failure can close an application before unsaved changes have been stored. Saving at regular intervals writes the latest work to the storage device, so less work is lost. Removing a password, switching off a mouse, or folding paper does not protect an unsaved digital document.

Correct answer: A. Both original and backup may be lost

A backup is useful only when it provides a separate recovery copy. If both the original data and its backup are stored on the same stolen device, one theft can remove both copies at once. Important data should also be backed up on a separate drive, trusted cloud location, or other protected place, with access secured appropriately.

Correct answer: A. Temporary memory

Unsaved edits are usually held temporarily in working memory or application buffers before they are written to permanent storage. A sudden power failure can therefore remove those changes, even though previously saved files may remain on the storage device. Saving regularly or enabling recovery features reduces the loss. The other memory and paper options do not explain the situation.

Correct answer: A. The item no longer remains in the Recycle Bin

Deleted files that are still in the Recycle Bin can usually be restored through the normal Restore command. Emptying the bin removes that convenient recovery location, so the file is no longer available there for ordinary restoration. Recovery may then require a separate backup or specialised recovery method and is not guaranteed. Therefore, important files should be checked before emptying the bin.

Correct answer: A. Both original and backup may be lost

A backup is useful only when it provides an additional recovery copy. If both the original data and its backup are stored on the same stolen device, one incident can remove both copies. A safer plan keeps another copy on a separate device or trusted location and, when appropriate, uses more than one backup method.

Correct answer: A. Save the important document

Closing an application may discard changes that have not been saved. Therefore the important document should first be saved, and the user should confirm that the saved copy is in the intended location. After that, unnecessary programs can be closed to free memory and processing resources. Sharing passwords, deleting files, or cutting power is neither necessary nor safe.

Correct answer: A. Both original and backup may be lost

A backup is useful only when it provides an independent way to recover data. If the original and its backup are stored on the same stolen device, one event can remove both copies. Keeping another copy on a separate device or secure location, and testing it periodically, gives much better protection against loss.

Correct answer: A. Temporary memory

Unsaved work is usually held temporarily in working memory and application buffers before it is written to permanent storage. A sudden power loss can therefore remove recent changes. Saving often, enabling recovery features, and using a backup power source where suitable reduce this risk. Permanent storage is less directly involved in unsaved changes.

Correct answer: A. Both the original and the backup may be lost

A backup is useful only when it provides an additional way to recover data after loss or damage. If the original files and the backup are stored on the same stolen device, one event can remove both copies. Important data should therefore have another copy on a separate device or suitably protected location. The other options have no connection with theft or backup.

Correct answer: A. Temporary memory

Unsaved edits are normally held temporarily in working memory and in the application's current session. When power is lost, those edits may disappear before they are written to permanent storage. Saving frequently, enabling recovery features, and using suitable backup power can reduce the risk. Permanent storage is not the best match for unsaved work.

Correct answer: A. Save the important document

An open document may contain changes that have not yet been written to storage. If an application is closed forcefully, those changes can be lost. Saving the important document first protects the work; after that, unnecessary applications can be closed normally to release memory and processing resources. Sharing a password, deleting files, or cutting power is unsafe and unnecessary.

Correct answer: A. It helps close open work and the system safely

A normal shutdown gives applications a chance to save work, close files, finish pending operations, and stop system services in an orderly way. Directly removing power can lose unsaved data and, in some situations, interrupt storage operations or cause system errors. Proper shutdown is therefore the safer routine method.
